Application filed fictober 27, 1919. Serial No. 333,660.

T 0 all whom it may concern Be itknown that 1, JAMES H. HARRIMAN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Miter- Blocks and Gages, of which the following is a specification.

The object of the present invention is to provide an improved reversible miter clamp or block for holding linotype slugs, or borders used in printing advertising matter, in newspapers or the like, for the purpose of cutting off said slugs or borders at an angle; and also an improved gage for use with said block.

In the accompanying drawing, Figure 1 is a perspective view, showing my improved miter block and gage in use adjacent to a Miller saw gage; Fig. 2 is a bottomplan view of the gage; Fig. 3 is a broken side view of said gage; Fig. 4 is a sectional view on the line 4-4 of Fig. 5; Fig. 5 is a plan view of my improved miter block; Fig. 6 is an edge view of the wedge portion. of said miter block, looking obliquely at a right an gle thereof; Fig. 7 is a broken plan View of the miter block reversed; Fig. 8 is a broken plan view of the miter block in use,

showing also an auxiliary gage in use; Fig. 9 is a perspective view of a gage; Fig. 10 is a broken plan view of another auxiliary gage; Fig. 11 is a sectional view on the line 1111 of Fig. 10.-

Referring to the drawing, 1 indicates a,

table of the lVIiller saw now commonly in use in composing rooms and printing oiiices;

The table is reciprocatory in the direction of the arrow a, while the saw is stationary. On said table is secured, as shown at 2, a Millersaw gage 3. having a rail 4 at right angles to the direction of the general length of the gage. which has a row of indentations 6 engaged by a screw 7 on the traveling portion 8 of the gage, by means of which screw and indentations, the traveling portion 8 of the gage travels on a rail 9 parallel to the row of indentations. provedmiter block having straight edges 12, 13, at right angles to each other, the edge 13 pressing against the rail 9. It, has also an edge 14 making an angle of 45 with the edges 12,13. The miter block is formed with a rel-entrant angle of 45, that is to say, the edge 13 is extended rearwardly beyond the edge. 14 to form a backing or support 15 11 indicates my im-' for a wedge 16, which isin the form of a right-angled isosceles triangle, having an oblique edge 17 parallel with the edge 14. One, 18, of the short sides of said wedge moves in contact with the front edge of said backing and is slidably held in position in contact therewith by screws 19 screwed obliquely into said backing, the heads of which are contained in a channel 21, eniarged at intervals, as shown at 22, to receive the heads of saidscrews and opening at the end of said short side 18 into the other short side 20 of the wedge.

Into the'under side of the wedge-shaped portion of the miter block, as shown at 23 in Fig. 7 is screwed a screw 23 and into the upper side of the wedge near its corner is screwed a screw 24. Both of these screws are adapted to engage a curved slot 26 which is already in the'Miller .saw table to hold the miter block firmly in position against movement parallel with. therail 9.

In using this miter block, the borders (used for forming borders of advertising matter) or the linotype slugs, are placed between the oblique edges 14, 17, of the miter block and triangular piece with theirfaces directed upward and are cut off by the Miller circular saw, the miter block being broughtinto close proximity to the saw and the triangular wedge being pressed downward by hand or by a clamp 28 which is drawn down by means of a rod 29, said clamp and rod forming a part of the apparatus of the Miller saw table. Owingto the peculiar form of the triangular wedge and its pressure against the backing 15, it results that the edge 17 of said wedge exerts an approximately uniform pressure along the edge of said borders or slugs, holding the bordersor slugs securely in position. The ends of the borders or slugs are then cut off at an angle of 45.

7 To cut off the other end also at an angle of 45, the borders or slugs are reversed in direction, but are still held with theirfaces upward. and the miter block and wedge are reversed, and the out is then made at the other end. Theborders or slugs will then lie in a direction at right angles to their former direction, but they will be reversed in position in the miter block.

To cut off the borders or slugs at any length desired, the space between said edges 14, 17, may be filled in at the back of the borders or slugs with a plug or with other at a distance substantially equal to the thickness of the rail 350i the traveling portion of the Miller saw gage extending at right angles to the rail 9 thereof, so that the dependingribs, when placed on opposite sides of said rail, and in close contact there- 7 with, practically clamp said rail and are of the Miller saw gage.

moved therewith and with the movable part Thereby the wide end of the gage 31 moves over the miter block. Said wide end has depending from its under side at one corner thereof, a block 36, which depends into a groove 37 in the Miller saw gage between the rail 9 and the line of indentations, and guides said gage in its movement. The wide end oi this gage engages the rear ends of the borders or slugs in the space between the oblique edges 14 and 17, and advances the same through a distance corresponding, but not equal, to the distance moved by the gage.

A line of graduation marks 38 is provided on the top of the gage near the edge 14 to assist in ascertaining how much the borders or slugs are projected beyond the miter block and how much, therefore, will be out 011 by the saw. Aline of graduation 'marks 39 is also provided on the under side of the oblique edge of the wedge for a similar purpose. 7

Any number of borders or slugs can be placed in the space between the miter block and the triangular wedge to be cut at one time, depending upon the size ofthe interval between the miter block and wedge.

I also provide an auxiliary gage 41 hav' ing therein a groove 42 which fits over a inserted a pin 44, which depends into the rib 43 formed on the upper side of the main gage 31 along its front or wide edge and having two sides making angles of 45 with said rib.- 'Through said auxiliary gage, close to the point where said sides meet, is

space'between the oblique edges 14 and 17 and contacts with the oblique edge 14 of the miter block. It results from this contact and the engagement of the groove 42 'with the rib 43 of the main gage that, as the main gage is slid over the miter block in the direction of the rail 9, the auxiliary gage 41 is slid in the direction ofthe oblique edge 14 of the miter block. This auxiliary gage is of use forcutting off a plurality of slugs or borders at the same time, when one or more have to be cut off shorter than the others, for it is evident that, the nearer the border or slug is to the oblique edge 14 of the miter block, the shorter will it be cut oil. This auxiliary gage is retained in place when not in use by a pin 44, which is threaded at its lower end, being screwed in a socket 46 in the upper side of the main g in Figs. 10 and 11 is shown another auX- iliary gage. This gage consists of two parts, an inner part 52 and an outer part 53. The inner part is formed with a groove 7 54 to fit over the rib 43 of the main gage so that the inner part 52 can slide transversely to the rail 19, and is formed with an edge making an angle of 22% with said groove and with a groove 56 on its upper side parallel with said latter edge. The part 53 is formed on its under side with a rib 57 fitting in said groove 56 and with a groove 58 receiving the rib 59 between the groove 56 and oblique edge of the part 52 and with an edge 61 parallel with the rib 43 of the main gage. It is also formed with a depending pin 62 which depends in the space between the oblique edges 14, 17 and 'contactswith the oblique edge 14. When this pin .engages the oblique edge 140i the miter block, it advances at the same rate as the main gage, that is, as the Miller gage,and, therefore, the slug or border, advances at the same rate, which fact renders it easy to calculate the length of the slugs to be cut off. The miter block is formed with an oblique groove 63 at the inner end of the oblique edge 14 to receive the lower end of the pin 62. i
